Firstly, since we're talking about probabilities I wouldn't use the word equally unless it meant exactly that. If it's not possible for life to just start under the right circumstances, then how did we get here - would that mean there is a god? Ignoring that for a moment, let's just go with the...
But is it possible that that kind of discovery ever be made? If the answer is yes it's possible, then that means there's much more chance of finding life on a googol of planets than on a few. I'll explain:
A) Chance of it not being possible for life to just start in the right atmosphere etc =...
I'm saying that this: "So no, it does not matter if there was a googol of planets, or just 42 - the likelihood of there being life elsewhere according to current knowledge remains the same." shows a lack of understanding of probability.
Say for example, that scientist discover that with...
That doesn't quite make sense*. The properties of our planet could be extremely rare, and mean that intelligent life isn't a given, but those properties aren't all required for basic life. For that you don't need much more water.
Saying 50/50 is just lazy. If we had the only galaxy in the...
I take it then that you have given it a lot of thought, and you're saying life elsewhere isn't inevitable. Can you explain why?
And even then, they'd be too far away for us to communicate with them.
What the **** have you done!
